the equation for compound interest is
we will see if it doubles or not
if t=1, we get A=P(1+r)
if t=2, we get A=P(1+r)^2
2(P(1+r))=P(1+r)^2 ?
2(1+r)=(1+r)^2 ?
2+r=r^2+2r+1
etc
when r=-1.618 or 0.618, then it doubles, but not when r is different things
not always
so no, it does not always double the amount of interest earned
Answer:
a) p=0.021
b) p=0.029
c) Exactly one audit: P=0.0965
More than one audit: P=0.0042
Step-by-step explanation:
a) If the income is less than $100,000, there is a probability of 21 in 1,000 of being audited. This is:
If the income is equal or more than $100,000, there is a probability of 29 in 1,000 of being audited. This is:
b) If we have 5 taxpayers with incomes under $100,000, and we want to know the probability that exactly one will be audited, we can model this a binomial randome variable, with p=0.021 and n=5:
There is a probability of 0.0965 that exactly one out of a sample of five taxpayers with incomes under $100,000 will be audited.
To calculate the probability that more than one will be audited, we use the same distribution:
There is a probability of 0.0042 that more than one out of a sample of five taxpayers with incomes under $100,000 will be audited.
I’ll give you the awnser from them all, but the show your work from just one. Hopefully you can figure it out. If not, reply with specific things you don’t understand and Ill try to talk it out with you. I struggled alot with this stuff when I was in your age too.
5) The answer is x = 3/4 or x= 0.75
12) x = 4
15) x = 2
